BEIRUT - Thousands of Syrians chanted "Death to America" on Saturday during funeral processions in Damascus for at least 44 people killed in twin suicide bombings that rocked the capital.Syria blamed al-Qaida for the blasts which hit two security buildings on Friday and came a day after an Arab League delegation arrived to prepare for monitors who will report on Syrian President Bashar Assad's implementation of a plan to end the bloodshed.Some Assad opponents said the attacks could have been staged by the government itself.The funerals on Saturday turned into pro-Assad rallies in which mourners called for revenge and condemned Qatari Foreign Minister Sheikh Hamad bin Jassim al-Thani whose country, once an ally of Assad, is now one of his main critics.
